Monitoring the performance of a filtration system processing thick gels requires instrumentation that can withstand high viscosity without compromising measurement accuracy or process hygiene. Traditional pressure ports often feature internal cavities that trap material, leading to blockages and erroneous readings. To solve this, a specialized digital pressure measurement solution was implemented to ensure continuous flow and reliable data acquisition.
- Flush-mounted diaphragm to eliminate media entrapment and dead space.
- Advanced data logging for real-time monitoring of filtration efficiency.
- Modular sensor design for rapid maintenance and range interchangeability.
- High-resolution digital display providing local and remote data visibility.
A manufacturing facility encountered a specific technical challenge while monitoring a filtration line used for a thick gel media. The primary concern for the process engineer was the potential for the gel to accumulate in the recessed port of a standard pressure gauge. In such applications, stagnant material within the internal cavity can harden over time, effectively insulating the sensing element from the actual process pressure and creating a significant maintenance burden. To ensure the integrity of the filtration line, a solution was required that offered both high-precision accuracy and a sanitary-style interface to prevent any hang-up of the media.
The technical solution centered on the implementation of the DM 01 series, a modular digital gauge that utilizes a flush diaphragm sensing element. Unlike standard configurations, this design aligns the sensing diaphragm directly with the process connection, creating a dead space-free environment. This is particularly critical for viscous fluids or pasty substances like gels, as it removes the risk of material stagnation. The gauge’s modularity provides a unique advantage for research and process engineers, allowing the display head and the pressure sensor modules to be swapped independently. This flexibility enables the use of different pressure ranges on the same filtration line or the replacement of a sensor for calibration without decommissioning the entire digital unit.
For data-driven process analysis, the integration of digital logging capabilities proved essential. The system features an internal memory capacity capable of recording over 600,000 individual pressure and temperature data points. By utilizing a specialized USB converter and accompanying software, the user can stream measurement data directly to a laptop in real-time or download logged histories for analysis in standard spreadsheet formats. This capability allows for the close monitoring of filtration trends and the identification of potential filter blinding or pump irregularities. The use of FKM seals further ensures chemical compatibility with various industrial gels, providing a robust and versatile measurement tool for demanding industrial environments.
